Hi,
A code segment from Itanium platform.
Note the instruction at 0x4000000000000722, what does this mean?
I'vd gdbed the program, r2=0, so 0x4000000000000722 just not executes.
This puzzles me because I am working on analyzing elfs depends on br
Instructions. Can I call into the internal of a function?
Thanks,
Zhenyu
